WebbFattore di Landé. In fisica, in particolare in meccanica quantistica, il fattore di Landé, anche detto Landé g-factor o fattore g di Landé, è un particolare tipo di fattore-g dato dal rapporto tra il momento magnetico e il momento angolare orbitale di un sistema, quale ad esempio una particella elementare in un nucleo atomico . Webb(1) Δ E = g β B where β is the constant, Bohr magneton. Since the energy absorbed by the electron should be exactly the same with the state energy difference ΔE, ΔE=hv ( h is Planck’s constant), the Equation 1 can be expressed as (2) h ν = g β B People can control the microwave frequency v and the magnetic field B.

WebbIn physics, the Landé g-factor is a particular example of a g-factor, namely for an electron with both spin and orbital angular momenta.It is named after Alfred Landé, who first described it in 1921.. In atomic physics, the Landé g-factor is a multiplicative term appearing in the expression for the energy levels of an atom in a weak magnetic field. ... Webb18 okt. 2009 · The g-factor was introduced by Goudsmit and Uhlenbeck to account for the behavior of an electron in a magnetic field because naive models of the electron do not give the proper magnetic dipole moment. g is measured experimentally via the precession of the spin vector. As you probably know, Dirac's theory predicts g = 2.
